The Sentry UL range provides automatic, current limited and thyristor controlled charging of vented lead acid or NiCd batteries. The units may be used in a wide range of industrial charging applications, including standby engines, pumps and generators.

The charger uses an open frame construction, designed for surface mounting in an enclosed panel. Each unit consists of a transformer, rectifier and control circuit. The control circuit ensures that the charger maintains a battery voltage at the pre-calibrated float level, while supplying any additional load current up to the specified maximum.

When used as a float charger, the unit is designed to give a constant current output while battery voltage is below a ‘knee point’ (approx. 13V on a 12V LA). Above the knee-point, as the battery approaches its float voltage, the Sentry output current ramps down. This multi-stage charge regime gives an optimum combination of fast charge rate, followed by float charge without overcharging.

The SMPS is a constant output voltage, current limited, battery charger specially designed for permanent connection to genset starter batteries.

Open chassis, metal cased design is suitable for bolt and stud mounting in an enclosed panel.
